Preparation method of high-strength foamed lightweight concrete
The invention belongs to the technical field of building materials, and particularly relates to a preparation method of high-strength foamed lightweight concrete. The high-strength foamed lightweight concrete comprises the following components in parts by weight: 50-55 parts of titanium gypsum powder, 18-22 parts of slag powder, 20-25 parts of Portland cement, 1-1.5 parts of a foam stabilizer, 1-1.5 parts of a cement foaming agent, 0.5-0.8 part of a water reducing agent, 0.8-1.2 parts of nitrogen-doped silicon dioxide and 0.5-0.8 part of nanometer zinc oxide powder. According to the invention, the addition amount of water, titanium gypsum powder, slag powder and Portland cement is accurately controlled through a calculation formula, so the wet volume weight of slurry is accurately controlled, open pores in the foamed concrete is greatly reduced, and the strength and impermeability of the foamed concrete are improved.
本发明属于建筑材料技术领域，具体涉及一种高强度泡沫轻质混凝土的制备方法，按照重量份数计算，包括如下组分：钛石膏粉50~55份，矿渣粉18~22份，硅酸盐水泥20~25份，稳泡剂1~1.5份，水泥发泡剂1~1.5份，减水剂0.5~0.8份，氮掺杂二氧化硅0.8~1.2份，纳米氧化锌粉末0.5~0.8份，本发明通过计算公式精确控制水和钛石膏粉、矿渣粉以及硅酸盐水泥加入量，从而精确控制泥浆湿容重，使发泡混凝土中的开放的气孔率大大减少，提高发泡混凝土的强度和抗渗性能。
